The glassfish.org website was redesigned as well. It looks clean and fresh.
I'm using Glassfish v4 for a while in daily development--it looks promising. Glassfish v4 also ships with NetBeans (JavaEE). With NetBeans and Glassfish you will get the most efficient JavaEE 7 environment to start (double click, wait 2 minutes) and to develop your applications (everything you need comes out-of-the-box--without any plugin hell).
